| 中文摘要: |
| 采用X射线荧光显微仪和X射线荧光镀层测厚仪，以及K值计算法，对银饰品中银含量、镍覆盖层厚度和样品总厚度进行检测研究。银含量检测的结果与国家标准溴化钾容量法(电位滴定法)(GB/T 17832-2008)的检测结果吻合。 |
| 英文摘要: |
| X-ray fluorescence microscope analyzer and X-ray coating thickness meter were used to study on testing of silver content, nickel coating thickness and jeweler thickness of silver jeweler. Among those, K value calculated method was applied to obtain the results of silver contents, which were almost equal to the results by national standard volumetric(potentionmetric) method using potassium bromide (GB/T 17832-2008). |
